I have an array as follows

Array
(
    [0] => 15/11/2012 - 18/11/2012
    [1] => 15/11/2012 - 18/11/2012
    [2] => 15/11/2012 - 18/11/2012
    [3] => 15/11/2012 - 18/11/2012
    [4] => 19/12/2012 - 24/12/2012
    [5] => 24/12/2012 - 01/01/2013
    [6] => 24/12/2012 - 01/01/2013
    [7] => 16/01/2013 - 01/02/2013
)

I am using array_unique to remove the duplicates which is giving me

    Array
(
    [0] => 15/11/2012 - 18/11/2012
    [4] => 19/12/2012 - 24/12/2012
    [5] => 24/12/2012 - 01/01/2013
    [7] => 16/01/2013 - 01/02/2013
)

How can I change the keys so that they are consecutive - as below

    Array
(
    [0] => 15/11/2012 - 18/11/2012
    [1] => 19/12/2012 - 24/12/2012
    [2] => 24/12/2012 - 01/01/2013
    [3] => 16/01/2013 - 01/02/2013
)

thanks in advance

Answer

Easiest way would be to put them into a new array either via a loop, or better yet array_values function.

$new_array = array_values($original_array)
